The water-to-cement ratio in concrete is a critical factor affecting its strength and durability. It's calculated by dividing the weight of water by the weight of cement in a mix. The ideal ratio typically ranges from 0.35 to 0.50, with lower ratios yielding stronger concrete. Too much water weakens the mix, while too little can make it ...Web

The concrete weight can vary depending on the air and moisture content it contains. Cement density (weight) can be 830 - 1650 kg per cubic meter or 52 - 103 lbs per cubic foot. Cement that is pneumatically loaded into silos is less dense while cement that has been stored and exposed to vibration, like being transported, is more dense.Web
